[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a CCD vision alignment and bonding device for FPC protective film, including a base plate 1, an adjustment component 7 above the base plate 1, a vacuum stage 8 above the adjustment component 7, the vacuum stage 8 facilitates the placement and adsorption of the FPC, increasing the positional stability of the FPC during bonding, an adsorption component 5 above the vacuum stage 8, the adsorption component 5 including an equipment box 501, an adsorption plate 502 and suction cups 503, the suction cups 503 are used to adsorb the FPC protective film, the adsorption plate 502 is located below the equipment box 501, four suction cups 503 are provided and fixedly installed at the four corners below the adsorption plate 502, mounting platforms 10 are fixedly installed at the front end, rear end and sides of the equipment box 501, a CCD vision camera 11 is fixedly installed below the mounting platform 10, and an intelligent processor 14 is fixedly installed inside the equipment box 501.

[0024] By setting up multiple sets of CCD vision cameras 11, the relevant image information of the bonding position between the FPC protective film and the flexible circuit board can be captured in real time from multiple angles. This multi-directional visual inspection structure can capture the position information of the flexible circuit board and the protective film in real time from multiple directions during the bonding process. The intelligent processor 14 can quickly analyze and process the acquired image data to accurately determine whether the two are aligned. Once a positional deviation is detected, it can promptly provide feedback to adjust the position of the relevant components, which helps to improve the bonding accuracy, effectively avoids bonding problems caused by misalignment, reduces the number of rework, and thus improves the bonding efficiency of the FPC protective film.

[0025] Please see Figure 1 and Figure 2Above the equipment box 501, there is a screw box 3. A ball screw is rotatably installed inside the screw box 3. A servo motor 6 is fixedly installed on one side of the screw box 3. The output end of the servo motor 6 is fixedly connected to the ball screw. A sliding block is slidably installed on the outside of the ball screw through a ball nut. The sliding block is fixedly connected to the equipment box 501. Side plates 4 are symmetrically fixedly installed at the front and rear ends of the screw box 3. A support plate 2 is fixedly installed below the side plate 4. The lower end of the support plate 2 is fixedly connected to the base plate 1.

[0026] When the servo motor 6 starts, it can drive the rotation of the ball screw, which in turn drives the sliding block to move smoothly along the ball screw. Since the sliding block is fixedly connected to the equipment box 501, the movement of the adsorption component 5 is realized, which is beneficial to the picking of FPC protective film and increases its practicality.

[0027] Please see Figure 1 and Figure 3 The adjustment assembly 7 includes a base plate 701, a lead screw 702, a side plate 703, a second base plate 704, a stabilizing column 705, and a mounting plate 706. The first base plate 701 is fixedly installed below the vacuum stage 8. Two side plates 703 are provided and are respectively located on both sides of the first base plate 701. The lead screw 702 is rotatably installed between the two side plates 703, and the lead screw 702 slides through the first base plate 701 through a ball nut. A second servo motor 12 is fixedly installed on one side of the right side plate 703, and the output end of the second servo motor 12 is fixedly connected to the lead screw 702. Next, base plate 2 704 is set below base plate 1 701. There are two mounting plates 706, which are symmetrically set at the front and rear ends of base plate 2 704. There are two stabilizing columns 705 and they are fixedly installed on both sides between the two mounting plates 706. The stabilizing columns 705 slide through base plate 2 704. The mounting plates 706 are fixedly connected to base plate 1. An electric cylinder 13 is fixedly installed at the rear end of the rear mounting plate 706. The push rod end of the electric cylinder 13 slides through the mounting plate 706 and is fixedly connected to base plate 2 704.

[0028] When servo motor 12 is started, the rotation of lead screw 702 can drive base plate 701 to move horizontally along the direction of lead screw 702, thereby realizing the horizontal position adjustment of vacuum stage 8. Through the extension and retraction of electric cylinder 13, base plate 704 can be driven to move longitudinally under the guidance of stabilizer 705, thereby realizing the vertical position adjustment of vacuum stage 8. This multi-directional adjustment capability enables the device to automatically adjust the position of flexible circuit board on vacuum stage 8, which is beneficial to the accurate bonding of FPC protective film.

[0029] Please see Figure 2Long hoses 9 are provided at the four corners above the adsorption plate 502. The four long hoses 9 are connected to the four suction cups 503 respectively. Inside the equipment box 501, there is an air pump 1 connected to the long hoses 9 and an air pump 2 for working on the vacuum stage 8. Both air pump 1 and air pump 2 are electrically connected to the intelligent processor 14.

[0030] When the air pump is started, it can provide a stable negative pressure to the suction cup 503 through the long hose 9, thereby firmly adsorbing the FPC protective film under the suction plate 502. At the same time, the air pump 2 set inside the equipment box 501 is used for the operation of the vacuum stage 8, providing the required vacuum environment for the vacuum stage 8, ensuring that the flexible circuit board is stably placed on the vacuum stage 8 during the bonding process, which increases its practicality.

[0031] Please see Figure 2 An electric cylinder 17 is fixedly installed in the middle of the equipment box 501. The push rod end of the electric cylinder 17 slides to the bottom of the equipment box 501 and is fixedly connected to the adsorption plate 502.

[0032] This enables the electric cylinder 17 to drive the adsorption plate 502 to move up and down, which is beneficial for the bonding of the flexible circuit board and the FPC protective film.

[0033] Please see Figure 4 The input terminal of the intelligent processor 14 is connected to the output terminal of the CCD vision camera 11. The output terminal of the intelligent processor 14 is connected to the input terminals of servo motor 11, servo motor 212, electric cylinder 13, wireless transmission module 15 and electric cylinder 217 respectively. The output terminal of the wireless transmission module 15 is connected to the input terminal of the external terminal 16 of the device.

[0034] The input end of the intelligent processor 14 is connected to the output end of the CCD vision camera 11, enabling it to acquire real-time image information of the bonding position between the FPC protective film and the flexible circuit board captured by the CCD vision camera 11, and perform rapid and accurate analysis and processing to provide precise decision-making basis for subsequent bonding operations. The output end of the intelligent processor 14 is connected to the input ends of servo motor 6, servo motor 12, electric cylinder 13, wireless transmission module 15, and electric cylinder 17, respectively, so that the intelligent processor 14 can drive the movement of each component according to the analyzed and processed image information, realizing functions such as moving the adsorption component 5, adjusting the vacuum stage 8, and adjusting the position of the adsorption plate 502, ensuring the automated and intelligent operation of the entire bonding process and increasing its practicality.

[0035] Working principle: During use, after the device is started, the air pump is activated, providing a stable negative pressure to the suction cup 503 through the long hose 9, firmly adsorbing the FPC protective film under the suction plate 502. Then, the flexible circuit board is placed on the vacuum stage 8 and adsorbed and fixed. Subsequently, the intelligent processor 14 receives the image information of the bonding position between the FPC protective film and the flexible circuit board captured in real time from multiple angles by the CCD vision camera 11, and quickly analyzes and processes it to determine the alignment between the two. If there is a positional deviation, the intelligent processor 14 immediately feeds back information and drives the corresponding components to adjust. When adjusting the position of the flexible circuit board on the vacuum stage 8 to achieve accurate bonding, the servo motor 12 is started, and the lead screw 702 rotates, driving the base plate 701 to move horizontally along the lead screw 702, thereby adjusting the horizontal position of the vacuum stage 8. At the same time, through the extension and retraction of the electric cylinder 13, the base plate 704 is driven to move longitudinally under the guidance of the stabilizing column 705, thereby adjusting the longitudinal position of the vacuum stage 8, so that the FPC protective film and the flexible circuit board are accurately aligned. Then, the adsorption plate 502 is driven to move downward, thereby enabling the bonding of the flexible circuit board and the FPC protective film.
